This paper proposes a light-emitting diode (LED) driver based on a three-phase resonant switched capacitor (SC) converter. The LED lamp employs chip-on-board (COB) technology, as it is possible to achieve high power density. The three-phase structure provides low ripple current and reduced percent flicker. Besides, it does not use electrolytic capacitors, thus, causing the driver lifetime to increase. The converter active switches are turned off under zero current switching (ZCS) and zero… CONTINUE READING
